SPECIFICATION forming part of Letters Patent No. 539,455, dated May 21, 1895. l

\ Application filed September 26,1894- Serial No. 524,164. (No model.) I

To all whom it may concern:

. Be it known that I, ARTHUR T. TIMEWEILL,

a citizen of the .United States, residing'in Spokane, in the county of Spokaneand State of Washington, have invented a new and useful Improvement in Sack Filling'and Sewing Machines, of which the following is a specification.

My invention relates to apparatus for fill- Io ing sacks or bags with grain or other material, and closing or sewing the months of the sacks or bags after they have been filled.

The object of my invention is to provide an automatic machine or apparatus of a simple and efficient construction,by means of which sacks or bags may be rapidly, conveniently and evenly filled, each with afixed or measured amount of material, the mouths of the sacks or bags securely sewed, and the filled and sewed sacks or bags discharged from the machine; and, to this end my invention consists, primarily, in the combination with a filling and weight or bulk measuring mechanism for delivering the'requisite quantity of grain or other material into each sack, of an opening and closing movable or traveling sack holder for holding the sack open while being filled, closing the same and holding it closed while being carried past the sewing mechanism and sewed, a sewing mechanism fixed on the frame of the, machine, and a conveyor mechanism for supporting and conveying the filled sack from the filling position past the sewing mechanism and discharging the filled and sewed sack from the machine.

It also consists,-in connection with a stationary sack filling device and a stationary sewing device or mechanism, of a series of two or more similar movable or traveling and opening and closing sack holders to enable one sack to be filled and another sewed and discharged at the same time, thus greatly increasing the capacity of the machine.

It also consists, in connection with the filling device and stationary sewing mechanism, of a sack holder and a track or way along which the sack holder travels on the machine, and the carrier for supporting and conveying the filled sack in an upright position under and 50 past the sewing mechanism, of yielding or spring supports for said carrier, so that the yielding of the carrier may compensate for any variation or inaccuracy in the action of the co-operative filling mechanism. By combining with the stationary sewing mechanism and sack conveyer a filling mechanism which operates to deliver an approximately measured quantity to each bag, I, in a great measure, prevent any considerable variation in the height or length of the filled bag and the 6: consequent weight-or strain of the filled bag orits holder against the sewing mechanism or its supports; but to further perfect the machine and guard against danger of injury to or stopping of the mechanismby the attempt to pass through the machine filled bags of undue height or length, I mount the bag carrier, or that portion of it which conveys the bag under the sewing mechanism, on springs or yielding supports, so that the distance or space between the carrier and the table or frame upon which the sewing mechanism is mounted and along which the bag holder travels, may automatically accommodate itself to the length or height of the filled-bag. My invention further consists, in connection with the bag filling mechanism and opening and closing traveling bag holder, of the track or way along which the bag holder travels, and a device or mechanism for moving said bag holder along said track or way into engagement with which the bag holder is thrown by the act of closing the same.

-It further consists, in connection with the filling mechanism, sewing mechanism, and traveling bag holder, of a device for automatically cutting the thread and holding the severed end of the thread.

It also consists, in connection with the filling mechanism and sewing mechanism and series of bag holders, of a track or way along which the bag holders travel from the filling position past the sewing mechanism to the discharging position, said .track or way for the holders having an open mouth at the discharge 5 end of the machine so that no injury can result to the mechanism by one holder following another successively. a

It further consists, in connection with the bag filling mechanism and sewing mechanism, ro: of an open and closing traveling sack holder furnished with movable or withdrawable hooks or teeth for engaging the mouth of the sack to facilitate the automatic discharge or disengagement of the sack from the holder after the sack has been sewed.

It further consists in the novel construction and combinations of parts and devices herein shown and described, and specified in the claims.

The filling and measuring mechanism, which operates to fill each sack to a fixed or measured extent, coacts directly with the holder to enable it to properly close the sack, which it could not do without danger of breakage if the sack were accidentally filled too full; also directly with the sewing mechanism and especially with the needle and looper thereof, which cannot properly operate it the sack is filled too full; and also with the sack conveyor and track for the holder between which the sack must pass, and between which it cannot pass properly if filled much too full. The combination of a measuring sack filler with the other parts it will thus be seen is necessary or important for the proper and successful operation of the other principal parts; and the mutual coactive relation and co-operation of the several parts are close and interdependent upon the several parts. In this connection it should also be observed that by combining a series of holders with the other principal parts, each of the holders cooperating in turn with each of the other principal parts, and the other principal parts being at the same time so arranged and combined as to permit the several holders to co-operate simultaneously therewith, the capacity of the machine as a whole is many times increased, one bag thus being filled while another is being sewed and still another being discharged from the machine.

In the accompanying drawings, which form a part of this specification, I have illustrated at Figures 1 and 1, in side elevation, a machine embodying my invention. Fig. 2 is a plan view somewhat enlarged. Fig. 3 is a partial vertical section taken on line 3 3 of Fig. 1. Fig. & is an enlarged detail vertical crosssection through the sewing mechanism on line 4 4 of Fig. 2. Fig. 5 is an enlarged detail plan View of the sewing mechanism. Fig. 6 is an enlarged plan view, partly in section, of one member of the thread cutter and holder. Fig. 7 is an enlarged detail plan view of the sack-holder, showing the same open. Fig. 8 is a similar view showing the same closed. Fig. 9 is an enlarged cross-section on the line 9 9 of Fig. 8. Fig. 10 is a detail view illustrating the means or arrangement by which the closing of the bag-holder operates to throw it into engagement with the gear mechanism for propelling it along its track or way. Figs.

are indicated by. the same the filling and measuring device; 0, the sewing device or mechanism; D, the movable opening and closing bag holder; F, the slotted track or way along which the bag holder is moved.

G and H are carriers for supporting and conveying the bag past the sewing mechanism from the filling position to the discharging position, and K the thread cutting and holding device.

The bag filling and measuring device B is preferably one adapted to measure by bulk instead of by weight, and comprises preferably a measuring chamber or hopper B of a capacity corresponding to that of the bag, a discharge spout B a delivery spout B and two valves 13 B and an operating lever B, the upper valve and lever being long enough and arranged so that the upper valve is completely closed before the lower one begins to open. By this means a definite quantity of material is filled into each bag X.

The sewing device or mechanism 0 has a frame 0 upon which the needle, looper and other parts are mounted; and which frame 0 is fixed by suitable screws or bolts 0 to the frame A, or the top piece or table A of said frame A. The bolts 0 extend through only one end of the sewing machine frame 0, thus leaving the other end of said frame 0 free; so that the needle C and looper C and other cooperative parts of the sewing mechanism may not be affected or thrown out of proper engagement with, or relation to, each other by any vibrations of the frame A or its table A, as might be the case if the sewing machine frame C were supported or attached to the table A at both sides of the slotted track or way F.

The frame plate A has an opening A to receive the sewing device 0, as is clearly illustrated in Figs. 4- and 5, sothat the needle (J may reciprocate in said opening just below the upper surface of the table or plate A and across the slot fol the slotted way F, along which the bag holders D travel or move, so that the line of stitching is made just beneath the lower edge or surface of the bag holder. The sewing machine frame 0' is arched over the slotted way F to give room for the bag holders to pass between the same and the track F on the frame plate A.

The sewing mechanism may be of any suitable form or kind known to those skilled in the art. That however which I prefer to use in practicing my invention is illustrated in the drawings, and comprises a reciprocating needle 0 a continuously revolving looper G a presser foot 0 and suitable means for re ciprocating the needle and revolving the looper, consisting preferably of an upright, shaft C carrying a gear C provided with a crank pin 0 a pitman 0 connected at one end to said crank pin and at the other end to a crank arm C on a crank shaft C the other arm, 0 of which is connected by a pivoted link C with the needle bar 0 The same upright shaft 0 is provided with a gear 0 meshing with an intermediate gear 0 that meshes with a gear 0 on the shaft 0 of the looper.

The series of bag holders D, two or more in number, so that the bag in one may be filled while that in another is being sewed and discharged, each consists, preferably, of four bars D, D, D, D, hinged together at their ends by pivots D so that they may be opened to assume a diamond-shape, as illustrated in Fig. '7, or closed togetherin a straight line, as illustrated in Fig. 8. ,A spring D coiled around one of the pivots D serves to throw orhold open the holder normally. The holder D, or each of its hinged bars D, is provided with a series of 'movable or withdrawable hooks or pointed pins or devices d to engage the mouth edge of the sack. These movable or withdrawable hooks d on which the sack is hung, are preferably fixed to rock shafts (1', one on each bar D', by rocking or rotating which the hooks may be withdrawn or moved from engagement with the sack in order to discharge the sack from the holder. The hooks d or the rock shafts-d are preferably held in their normal positionthat for their withdrawal from the sackby springs d preferably coiled around the rock shafts and the rock shafts d are preferably rotated or rocked to throw the hooks into position for hanging the sack thereon automatically by the act of opening the holder to receive the sack. This automatic movement of the hooks from their sack discharging or withdrawing position to their sack hanging or receiving position may be accomplished by any suitable means of mechanism. A simple and convenient means for accomplishing this purpose is illustrated in the drawings, and consists in providing each of the hook bearingrock shafts d with a curved or cam-shaped arm at that engages projections 61 on the pivoted bars D, as is clearly. illustrated in Fig. 9, taken in connection with Figs. 7 and '8. The projection or part d on the bar D that is engaged by the opposite curved arm d is, as illustrated in the drawings, also. the bearing or housing for the rock shaft d. By this means, as the contiguous pivoted bars D D are thrown open or separated, the curved arm d engaging the projection d inclines the books at upward into position for conveniently receiving and hanging the sack thereon. As,- or when, the bars D D are closed the curvature or cam-shape of the arm at permits the springs d to throw the hooks d into a horizontal position, so that the further lateral opening or separation of the bars DD' withdraws the hooks d from the sewed seam of the filled sack. This will be readily understood from Figs. 9, 7, 8 and 2.

The track or way F on the top plate A of the frame A is provided with a longitudinal slotfto receive or accommodate the seam or the closed mouth edges of the bag. This slot fis enlarged at the filling station into a diamond-shaped opening f to receive and accommodate the open mouth of the bag at the time it is being filled. The track or way F for the holders D has an enlargement F at the filling station to receive or accommodate the holder in its open form, and another enlargement F at the discharge-end of the machine to permit the holder to open and the filled and sewed sack to be released from the holder; that is to say, the two side Walls f f of the track between which the holders pass,

conform to the closed form of the holder at that part of the track where the holders are being carried past the sewing mechanism, so

that these side walls will serve to keep the holder closed as well as to properly guide the same along; and these side walls f f diverge at the filling station F to give room for the holder when it is open; and these side walls f f again diverge at the discharge point F to permit the bars D of the holder to open to discharge the filled and sewed sack; The track F at the filling station has a closed end or abutment F against which the rear end of the holder D abuts, so that the act of closing the open holder will serve to project the front end of the holder forward and thus throw the holder into engagement with the mechanism for propelling the holder along the trackF. This is clearly illustrated in Fig. 10 in connection with Fig. 2. The track F has an open end or mouth F at its discharge end,so that one holder following another may not be obstructed or stopped by the holder ahead of it, as might be the case if the track F had an abutlnentor closed end at the discharge end of the machine.

The means for supporting and conveying the sack from the filling station past the sewing mechanism to the discharge position, consists preferably of two movable carriers G and H, in order to permit the bag to be conveniently shaken or vibrated up and down at the time it is being filled. Both these carriers are preferably of the endless belt type. To shake or vibrate the'bag up and down at the time it is being filled, the carrier G which supports the bag at this time and serves to move it onto the other carrier H, is mounted on an up and down movable or vibrating frame G, and to enable this carrier G and its frame to vibrate up and down conveniently, I furnish the same with a counter-balance G the counter-balance being preferably in the form of a coiled spring, connected at one end to the main frame of the machine and at the other to the vibrating frame G, the connection to the vibrating frame G being preferably made through the mechanism which supports and operates or vibrates the frame G. The frame G is supported and vibrated by the crank arm or lever G on the shaft G of the pulley or wheel G in connection with the rope or chain G attached at its two ends to the frame G passing over or around the pulleys or sprocket wheels G G The chain G is secured at an intermediate part of its length to IOO the periphery of the pulley G one strand of the chain passing directly down to one side of the frame G, and the other strand of the chain passing over the pulley G and thence down to the other side of such frame G, so that both sides of the frame may be raised and lowered evenly and simultaneously from the crank G. At the opposite end of the frame G a similar chain G as indicated in Fig. 3,is similarly arranged, so that the frame G is thus supported at each of its four corners by the chains G The carrier G travels on pulleys or sprocket wheels G G on shafts G, G journaled on the frame G, and the same is intermittently operated-that is to say, the carrier G remains stationary while the bag is being filled and is then set to moving or revolving in order to convey the filled bag onto the carrier H, which preferably moves continuously.

The carrier H travels on pulleys or sprocket wheels H, the shafts H of which are journaled on the frame H which is provided with yielding or spring supports 1-1 so that the frame H may yield or give when necessary, to give room for an abnormally high or long bag between itself and the top plate A of the frame or the bag holder track or guide F, mounted thereon. This insures against danger of stoppage, breakage or injury arising from the irregularlength orheight of the filled bags, and is a matter of importance and value in the practical operation of the machine, as I have found by my experiments.

The thread cutting and holding device or mechanism K, consists preferably of two sliding spring actuated bars 70, mounted on the frame plate A of the machine, and each provided with a pin or roller projecting in the path of the holders D in the track F, and each furnished with a knife or cutter 70 and thread holding jaw 70 so that theinstant the holder D passes the projection 70 the sliding bars 70 70, carrying the knives and thread holding jaws, will be actuated or closed against each other by their springs k and thus sever the thread and hold the free end of the same. hen the next holder advances into position for the bag therein to be sewed, the thread cutting and holding sliding bars 7c is are antomatically retracted into position for the succeeding operation.

Any suitable means or mechanism may be employed for closing the open holder D at the filling position after the sack is filled. That which I prefer is illustrated in the drawings, and consists of a pair of sliding bars M, M, mounted on the frame of the machine in suitable guides lV furnished with anti-friction rollers m m, adapted to engage the holder bars D D, and actuated by bell crank levers M M connected by rods M M with the levers M 31 which are pivoted together at m and to the frame at m m, and one of which is furnished with a treadle M so that the two slides M M are similarly and simultaneously operated.

Any suitable means may be employed for propelling or moving the holdersD along the track or way F from the filling position past the sewing mechanism to the discharging position. The means which I prefer to employ consists in the gears N N, mounted above the track F, one on each side of the sewing mechanism, and which engage rack N secured to the holders D. The act of closing the holder pushes the same forward and throws its rack N into engagement with the first gear N, as the holder is elongated by the act of closing the same. The gears Nare secured to shafts N having gears N which mesh with gears N on shafts N carrying gears N that mesh with the gear N on the driving shaft P The sewing machine may likewise be operated in any suitable manner, but preferably by a bevel gearP engaging the bevel gear 0 the bevel gear P being secured to a sleeve P which is thrown into gear with the driving shaft P by a sliding clutch p, which is operated automatically by an arm or lever 13 pro- 1 jecting into the track F in the path of the bag holder D. A spring 19 serves to retract the clutch and throw the sewing machine out of gear when the sewing of the bag is completed and the bag holder D is carried past said clutch operating arm 19.

The carrier G and the carrier H may both be conveniently driven by a single sprocket chain T, engaging a sprocket wheel T on the shaft N and extending over or around the sprocket wheels T T of the carriers G and H, and over or around the idlers T, T and T". The sprocket wheel T on the vibrating carrier platform G is thrown into engagement with the driving shaft of the carrier G by a sliding clutch g, having a pin g which fits in a stationary cam groove g attached to the frame of the machine, so that when the frame G is raised up to its full limit to bring the carriers G and H about on a level, the intermittently operating carrier G will be thrown into operation.

The operation of the machine is as follows: The bulk or weight measured quantity of material necessary to fill a sack being in the measuring chamber B of the filling mechanism B, and an open sack holder with sack attached being in position on the track F at the filling position F,the operator opens the lower valve of the measuring chamber or hopper and fills the sack, at the same time shaking the sack up and down if necessary by operating the vibrating carrier platformG with the lever G After the sack has thus been filled with a definite and measured quantity of material, the operator with crank G lifts the carrier frame G, and thus through the action of the clutch g sets the carrier G in IIO motion; and the operator, momentarily after this, withhis foot on the treadle M operates the sliding bars M and closes the bag holder D, and thus simultaneously throws the bag holder into engagement with its propelling mechanism or gear N. .The closed bag holder and bag are then conveyed,the former along the track F and the latter on the carriers G and H past the sewing.mechanismgfwhich is automatically set inoperationbythe movement of thefholderD along the track F, as befored'scribed. After the sewing is completed and the bag holder passes beyond the spring actuated thread cutting and holding device, the two opening and closing parts of this device automatically close and sever the thread from the bag, and at the same time grasp the free end of the thread. The bag holder continuing its movement along the track F, after passing the point where the side walls f f of the track diverge is then automatically thrown open by the spring D at one of the pivots of the holder; and as the bars D D of the holder open or separate, the hooks or pins (1 are withdrawn from the sack; and the further movement of the carrier H discharges the sack from the machine. In the meantime another holder of the series has been placed in the machine at the filling position and filled in the same manner, so that the operation is successively continuous.

The spring supports H for the carrier frame H are attached to the frame A through adjusting screws I-I so that the height of the carrier H may be adjusted for operation upon bags of different sizes or lengths.

The bars D of the holder D are preferably provided with serrations d on their meeting e ges.
